ATTORNEYS United States Patent 3,303,517 TOILET SEAT LIFTER Clyde M.Wood and Doris R. Wood, both of 1100 Som Center Road, Mayfield Heights,Ohio 45069 Filed Jan. 2, 1964, Ser. No. 335,176 12 Claims. (Cl. 4-251)This invention relates in general to improvements in seat lifters fortoilet bowls, and more particularly to a seat lifter which is adaptedfor ready connection to existing toilet bowls.

Foot actuated seat lifters for toilet bowls or water closets are knownin the art, to eliminate the necessity of raising the seat by means ofthe hands, either in the intrests of non-contamination of the hands, orwhere in hospitals and like facilities, the hands of the user may beoccupied, for instance, in carrying objects, and therefore are notavailable for raising the seat of the toilet bowl.

However, these prior art mechanisms have not been entirely satisfactoryin that they are generally unduly bulky, occupying an excessive amountof space in conjunction with the toilet bowl, and usually materiallycomplicate the cleaning of the bowl and the area around the bowl.Moreover, such seat lifters have usually had to be used with aparticular design or brand of toilet bowl, and many times are notuseable with generally all standard types of toilet bowls.

The present invention provides a novel seat lifter mechanism which isadapted to be actuated by the foot of the user to raise the seat of atoilet bowl and maintain it in raised position and which includes meansfor readily tripping the lifting mechanism and permitting the seat to belowered quietly to down position. The invention also provides a liftermechanism adapted to ready connection to generally all types and sizesoftoilet bowls, and a mechanism which results in minimum interferencewith cleaning operations on the toilet bowl and the area around thebowl.

Accordingly, an object of the present invention is to provide a novelseat lifter mechanism for toilet bowls.

Another object of the present invention is to provide a novel seatlifter mechanism which may be readily attached to existing toilet bowlswithout the necessity of having a custom made design of toilet bowl foruse with the seat lifter.

Another object of the invention is to provide a seat lifter for a toiletbowl which can be readily attached to existing bowls and whichfacilitates the cleaning of the area around the toilet bowl.

Another object of the invention is to provide a novel toilet seat lifterwhich comprises a linkage mechanism adapted to be operated by the foot,and with the linkage mechanism embodying an over center linkage action,whereby the seat may be held in a raised condition until the lifter isagain actuated to lower the seat.

A further object of the invention is to provide a seat lifter mechanismof the latter mentioned type including a fluid checking device forresisting the lowering of the seat upon actuation of the linkagemechanism, whereby the seat may be lowered without slamming down ontothe bowl.

A still further object of the invention is to provide a seat liftermechanism of the aforementioned type including novel means embodied withthe lifter mechanism for deactuation of the over center linkagearrangement, and causing the weight of the seat to act to lower the seatagainst the resistance of the checking device.

Other objects and advantages of the invention will be apparent from thefollowing description taken in conjunction with the accompanyingdrawings wherein:

FIG. 1 is a side elevational view of a toilet bowl embodying the instantseat lifter mechanism of the invention; in full lines there is shown alowered position of the seat and associated position of the liftermechanism, and in dot-dash lines there is shown a raised condition ofthe seat together with the associated position of only certain portionsof the lifter mechanism. I

FIG. 2 is an enlarged, generally perspective view of the seat liftermechanism and showing in the full lines the general condition of theparts of the mechanism when the seat is in a raised position, andshowing in dot-dash lines the general condition of the mechanism whenthe seat is in lowered position.

FIG. 3 is a reduced size, top plan, generally diagrammatic view of thetoilet bowl and associated seat lifter mechanism showing, in general,the positional relationship in plan of the parts of the lifter mechanismwith respect to the toilet bowl.

FIG. 4 is an enlarged, top plan view of the fluid checking mechanismwhich is adapted to resist the lowering of the seat.

FIG. 5 is a top plan view of the mounting plate of the seat liftermechanism which is adapted for attaching the lifter mechanism togenerally any known or existing toilet bowl.

FIG. 6 is an enlarged, side elevational view of an abutment memberadapted for attachment to the underside of the toilet seat as shown inFIGS. 1 and 2, for limiting the clockwise or upward pivoting of the seatwith respect to the linkage mechanism of the lifter arrangement.

' Referring now again to the drawings, there is ShOWn a water closet ofconventional, well known type having a bowl portion 10, a tank portion12, and with a seat 14 being hinged as at 14a to the conventional bridgeportion 16 of the bowl. The seat 14 is hinged to the bridge portion 16as by means of conventional seat lugs or bolts 18 attached to the seatand extending through openings in the bridge portion. NutslSa coactingwith the threaded lugs or bolts 18 from underneath the bridge portion,hold the seat in position in the conventional manner. Bumpers 19 areprovided on the seats underside as usual, and maintain the seat inslightly raised condition with respect to the top of the bowl 10 and inthe conventional well known manner.

Now in accordance with the instant invention a seat lifter mechanism 20is provided, mounted on the toilet bowl and coacting with the cover orseat 14, for lifting the seat upwardly upon manual actuation, as bymeans of a foot of the user. Such seat lifter mechanism may comprise afoot actuated main lever member 21 pivoted as at 21a to a column orsupporting rod member 22, a lifter link 24 pivoted as at 24a to thesupport 22, and adapted for engagement with the underside of the seat14, and a connecting link member 26 which is pivoted as at 26a to thelifter link 24, and as at 26b to the foot lever 21.

A fluid checking unit 28 may be pivoted asat 28a to supporting ormounting member 30, and the piston rod 29 of the checking unit may berather loosely coupled as at 34 to the associated apertured end of thefoot lever link 21. As may be seen, link 21 is a first class lever,while link 24 is' a third class lever.

The aforementioned mounting member may comprise a flat plate having anopening 36 in one diagonal end surface thereof for receiving therein apivot pin 37 (FIG. 4) secured to the checking unit 28 for pivotallymounting the latter on the plate. The checking unit pin 37 is preferablyreceivedin opening 36 with a slight frictional fit, but is adapted to bereadily pivoted in such receiving opening 36.

An L-shaped member 39 (FIGS. 2 and 3) is preferably adjustably mountedon the plate 30 over opening 39a therein, so that such member 39 may bepivoted about an axis perpendicular to plate 30. A screw or otherfastening means may coact between the underside of the plate'member 30and member 39, for adjustably holding the member 39 in selected fixed,position on the plate. Member 39 is adapted, to coact with the shelf orbridge portion of the toilet bowl in overlying engaged relation to aidin maintaining the seat lifter mechanism in mounted position on thebowl.

The supporting plate member 30 has an opening 40 therethrough (FIG. 5)through which extends the upper portion of supporting rod 22, andas bestshown in FIG. 2 of the "drawings. As can be seen, supporting rod 22 hasan offset or bent section 42 (FIG. 2) which enables a compact andexpeditious mounting of foot lever 21 on rod 22, and the readyconnecting of lever 21 with the checking unit 28. An opening 43a may beprovided in plate 30 forreceiving a pin which also extends. through acomplementary opening in rod 22, for locking the rod 22 in selectedposition with respect to plate 38.

Plate member 30 also has an opening 44 therethrough through which isadapted to extend one of the seat mounting lugs 18, and. then theaforementioned nutmember 18a coacts with the underside of the'plate 30and holds the plate in abutting relation withthe underside of the bridgeor shelf portion 16 of the bowl. Adjusting screws 46, 46a, 47, 48 and48a are preferably also provided in tr'eaded openings in the mountingplate 30, for tightening up and adjusting the position of the plate withrespect to the bowl when it is in mounted condition on the bowl. It wiilbe seen that screws 46, 46a and 48 are adapted to coact with theunderside of the shelf or bridge portion of the bowl, while screw 48a isadapted to coact with the generally rounded area or section 5% of thebowl, and screw 47 is adapted to coact with the section52 of the bowl,just below the bridge portion, and thus hold the mounting plate 30 invery secure, position on the bowl. By loosening up on nut 18:: andadjusting the screw rnembars 56, 46a, 47, 48 and 48a, the plate 30 canbe moved or swung with respect to the attaching seat lug 18, and thuseffectively adjust the position of the lifter mechanism on the bowl. p v

The lifter link 24 can be seen .to embody a bent distal end portion 49(FIG. 3) which extends inwardly in underlying relation to the seat 14,and which embodies a prew ferably rotatable washer or roller 58 thereon,which is adapted to roll with respect to the undersite of the seat, uponraising and lowering of the seat. In this connection there is providedan abutment lug 54 (FIGS. 1, 2 and 6) which is adapted to coact with theroller member 50 on the lifter link 24, and lock or limit the pivotalmovement of the seat with respectto the lifter linkage, and whichactually locks or secures the lifter linkage to the seat in the raisedcondition of the seat. From FIG. 6 it can be seen, that the lug 54embodies a mounting portion 56 which is adapted to abut with theunderside of the toilet seat and which is provided with an opening 56atherethrough for receiving a fastener for attaching the lug to the seat,and a sloped can portion 56b which receives and holds the roller memberon the lifter link 24, between portion 56b and the underside ofthe seat,aswill be hereiiiafter described in greater detail.

Referring now in particular to FIG. 4, the checking device 28 maycomprise a hydraulic cylinder 57 having the piston rod 29 extending outof one end of the cylinder, and having a pair of spaced piston headmembers 57a, 57b secured thereto. The piston head members may includeresilient washer-like members 58, 58a, which may be adjustably mountedon the piston rod by means of threaded nuts 59, for adjusting the spacebetween such members. The piston head members 57a, 57b define What willbe called an upper chamber 60, and a lower chamber 60a in the checkingmember. Washer member 58 has an opening or orifice 62 therethrough, andthrough which is adapted to flow the resistance fluid, such as oil, fromthe lower chamber to the upper chamber and vice versa, upon axialmovement of the piston rod and associated piston head members. Thepiston rod 29, as aforementioned, is rather loosely connected to thefoot lever 21, as by means of a wire 63 secured to the rod and extendingthrough an opening in the associated end of the main rod 21. v

The wire may be detachably connected to the lever 21 by laterally bentportion 63a after it passes through the receiving opening to form agenerally lost motion con nection. The piston rod and associated pistonhead members are moved outwardly of the cylinder to force the fluidwhich occupies chamber 60, 60a from the upper chamber to the lowerchamber, due to the fact that a vacuum is formed in the lower chamberupon the outward stroke of the piston rod, which condition actuallysucks the oil down into the lower chamber from the upper chamber 60 andvia orifice 62. An air breather hole 65 is provided on the upper end ofcylinder '57 and communicates the interior of cylinder 57 ahead of headmember 57a with the exterior. In this connection, the interior walls ofthe cylinder which slidingly coact with the resilient washer 5811 duringthe outward stroke of the rod 29 are tapered outwardly asat 65a, topermit entry of some air into upper chamber 60 during the outward strokeand resultant movement of oil into lower chamber 60a. Upon lowering ofthe toilet seat, and

. engagement of the rod 21 with the confronting end of the piston rod,the weight of the seat forces the piston rod and associated head member57a, 57b axially inwardly. of the cylinder, forcing the oil in the lowerchamber through the orifice 62 into the upper chamber, thus resistingthe flow of fluid from the lower chamber to the upper chamber, andthereby lowering the seat quietly down onto the top of the bowl 10.During such inward stroke, the intaken air in upper chamber 60 is forcedpast the resilient washer 58a into communication with the liftermechanism, he may push down on the pedal 66 I which is preferablyadjustably' mounted on the end of foot lever member 21 as by means ofthreaded shank and coacting nut 66a, for adjusting the vertical positionof the pedal 66 with respect to the lever 21, and which includes atripping means 68, comprising a generally S-shaped member which ispivoted as at 69 to a bracket 70 preferably secured to the shank of thepedal 66, and which S-shaped or cam member is. adapted for engagementwith the floor as shown in full lines in FIG. 2. A'pin 70a projectinglaterally from member 68 is adapted to limit counterclockwise movementof member 68.

Now as the foot level 21 is pivoted downwardly about its pivot point 21ato the support rod 22, and from the dot-dash to the full line positionof FIG. 2, this pivots the load endof the lever 21 in a counterclockwisedirection (with respect to FIG. 2) which due to its being coupled bylink 26 to the lifter lever 24, swings the lifter lever 24 upwardlyabout its pivot point 24a to the support rod 22. It will be seen that ina raised position of the seat, the roller 50 is coacting with lug 54 tolock the lifter mechanism to the seat, and the link 26 moves over centerso that upon release of the foot of the user from the foot pedal 66, theseat is retained in a raised position, due to the fact that pivot point26b of the link 26 has moved outwardly beyond the pivot point 26a of thelink, and therefore the weight of the seat is not effective to lower theseat. It will also be seen that upon such movement as aforediscussed,the checking unit 28 swings about its pivot point 37 from a more or lessvertical position as shown in dot-dash lines in FIG. 2, to the full lineposition, with the piston rod being extended.

Now to release the mechanism, and permit lowering of the seat, the footof the user can press down on the raised section 71 of tripping means68, which cams against the floor, thereby pivoting about its pivot point69 and causing raising or clockwise movement of the link 21 about itspivot point 21a to the support 22. This causes the rearward end of thelink 21 to move in a clockwise direction (with respect to FIG. 2)thereby pulling the link 26 back from over center and beyond the pivotpoint 26a of the link to the lifter link 24, whereby the weight on theseat causes the seat to lower against the resistance of the checkingunit 28.

It will be seen that the support member 22 preferably has a base blockor member 75 which comprises a pair of threaded screws 76, 7611 havingpreferably pointed ends 78, which engage the floor and support thesupporting rod 22. The threaded members 76, 76a may be rotated to raiseand lower their position with respect to block member 75, therebyproviding for the use of the seat lifter with different heights of waterclosets, as well as providing for leveling of the mechanism. Screwmember 80 extending in threaded relation through the support member 75locks the support rod 22 with respect to the base member 75, therebyholding the latter in whatever position is selected. In this connectionblock 75 may be slotted to give it a resilient gripping coaction withthe lower end of rod 22 received therethrough, and movement of the block75 along rod 22 adjusts the mechanism for use with different heights ofwater closets. It will be seen that the fact that the support rod 22 issupported by means of two spaced points 73 on the floor greatlyfacilitates the cleaning of the floor area about the toilet bowl, andenables the area to be readily maintained in sanitary condition.

It will also be seen that since all existing or standard toilet bowlshave a bridging portion 16 and connect the seat to the bridging portionby means of generally standardized threaded seat lugs 18, and that theposition of the lifter mechanism is readily adjustable with respect tothe bowl, such lifter mechanism may be readily connected to generallyall known brands of toilet bowls without the necessity of customdesigning the mechanism to any particular construction or brand of bowl.Likewise, by merely loosening up on clamp 39 and removal of nut 18a fromseat lug 18, the seat lifter mechanism can be removed from the watercloset.

While the iifter mechanism has been shown on the right hand side of thetoilet bowl, which is the preferred location, it will be understood thatit may be installed on the opposite side of the bowl.

From the foregoing discussion and accompanying drawings, it will be seenthat the invention provides a novel seat lifter mechanism which providesfor readily raising the seat by foot actuated means, and also providesfor tripping the lifter mechanism and permitting the seat to be loweredquietly to down position. The invention also provides a novel liftermechanism which is readily adapted for connection to generally allexisting types and sizes of toilet bowls, and results in minimuminterference with cleaning operations on the bowl, and the area aroundthe bowl. The invention also provides a lifter mechanism having a novelchecking means for resisting the lowering of the toilet seat, and onethat utilizes a vacuum for aiding in moving resistance fluid from onechamber to another chamber in the checking mechanism.
